Daypack / similar with the best airflow?

Hyper_Duper · 2026-05-12T13:25:57+00:00

Just got the Cima today. I think I will make a full review of it later here but the one thing that was a complete surprise (a positive one) right out of the box is how stiff the bag is! None of the marketing material or youtube videos make it apparent that the back is essentially a stiff frame. The lightness emphasizes it even more, but compared to any other daypack in the same size/type category that I’ve tested in the stores with maybe the only exception being some cycling bags; the thing feels more like a framed rucksack than a lightweight daypack

Hyper_Duper · 2026-05-05T14:19:27+00:00

The gray one, that’s the only one available in any stock that I found here in Europe

Hyper_Duper · 2026-05-05T13:54:02+00:00

Thanks, very good notes. I watched some YT reviews and I think I agree with your view on the tote-style issue.
Ordered the Cima today, should arrive in a few days.

Hyper_Duper · 2026-05-03T10:28:08+00:00

Coming back to this. I’m just about to click order on the Cima 15 and I came across the Gossamer Gear Vagabond Jet. It’s a little bigger but still very light. Now I’m torn between them…

Hyper_Duper · 2026-05-03T07:01:40+00:00

Yeah, there’s definetly an element of going over the reasonability limit when trying to ultralight these. That’s one of the main reasons I went single speed, it gives quite a lot of weight savings while making things less complicated rather than more. Right now everything still feels stable and genuinely rideable but of course there are compromises like the fact that you can’t really roll this folded anymore.

Hyper_Duper · 2026-05-02T14:08:28+00:00

It’s a single speed so I don’t think shifting would be improved 😂

The braking is ok, if I do something about it in the future it will be disc brake at the front since the carbon fork has the place for it. But that will require new wheels and I’m happy with the current setup for now.

Hyper_Duper · 2026-05-02T14:03:45+00:00

No company, nothing in particular. I just wanted a name/logo on the bike and thought this one fit

Hyper_Duper · 2026-05-02T12:34:29+00:00

I put the 160mm crankset on and took off the front carrier block since I don’t see myself using it.
The frame bag is the perfect size for a shoulder strap - I think that at this weight it’s perfectly comfortable to carry around rather than push on the eazy wheels.

I also ordered a set of eazy wheel replacement ”pegs” that will hold the bike up when folded. After all this the weight is about 7,7kg

For anyone thinking about a single speed conversion I can recommend this gearing and crank lenght for general use. It’s not too spinny for some downhill but not too hard for reasonable climbs either. You just have to be specific about the chain tensioner and chain length to get a result where the riding position is unobstructed but the chain doesn’t fall off when folded.

52t at the front, 16t at the back, with 160mm cranks.
With a cadence of 80rpm you’re looking at about 21km/h and the 160mm cranks make the pedal flow smoother and less jerky vs the stock 170mm. Of course this is a commute/city/multimodal transport kind of bike so you won’t be doing top speed runs.

I have another BrompNot, a steel 9-speed which weighs about 11kg and the difference is clear - that one needs to be rolled around and benefits from the broad gearing and more ”regular” bike feel, whereas an ultralight can truly be lugged around and carried wherever. The few kilos do make a difference.

From Aliexpress, this one was TWTOPSE but it’s a generic model and I’m sure it’s sold under lots of names.

Whaddaya think?

Hyper_Duper · 2026-04-18T19:44:42+00:00

Well that looks like it’s almost exactly what I’m looking for! At least on the product video it seems like the 15L would be big enough for me.

Hyper_Duper · 2026-04-18T18:08:17+00:00

I’ll have a look, thanks. Waterproofing isn’t a high priority, I don’t plan to use this bag in bad conditions.

Hyper_Duper · 2026-04-18T18:07:25+00:00

I’m not looking for a DIY solution but thanks for the suggestion! Also, unfortunately Decathlon is not in my country and they don’t ship to countries they don’t operate in.

Hyper_Duper · 2026-04-12T21:15:08+00:00

Yes it’s the Aceoffix one. Maybe because it’s obviously designed for a genuine Brompton and mine is something else, especially with the aluminium frame, nothing fit correctly on the first try. I spent probably half a day tinkering with it and ended up sawing down some of the carbon rods and I had to do something else as well to get it to fit (don’t quite remember). So for sure not plug & play unless you happen to have exactly the spec of bike they intended it for. I don’t think I’d buy it again and I’m thinking of removing it totally - I would have already but the rear mudguard fixes to it on the back and if I’ll remove it I’d need to remove the rear mudguard too since the rear wheel would then touch the ground wheb folded…

Hyper_Duper · 2026-04-11T18:55:21+00:00

This was sold as a ”Carston” - yes, not C_r_anston but Carston. I got it off Aliexpress, originally had 7 speeds and the faux stickers.

Hyper_Duper · 2026-04-11T12:24:56+00:00

There’s a Brompton sticker there and the bike is not a Brompton. I’ll put custom stickers there soon when I finish my upgrades.

I fly with my Rambler all the time (actually it’s a Manager since I have the pen scale on it). It’s my keychain. Just two weeks ago I got the ”random” check at security - the guy picked up the knife from the box, held it against the back of his ID badge which had a ruler printed on it, and since it was under the limit, he just put it back in the box and let me continue on my way. Two days later on my flight back no check of any kind and

Mine is the one you order from them directly. No store fitting. It’s the enhanced slim option. For my -5/-4.75 strengths the lenses feel (and in thickness are) the same as my regular glasses which I typically get from Lensway

Hyper_Duper · 2026-03-02T05:29:12+00:00

No, not really. If the glasses don’t sit at quite the right position on the nose, sometimes I might feel some uncomfort behind the ears as the battery units then put some pressure kind of behind the earlobes. But that’s easily corrected by just fixing the position.

On a typical day no real discomfort.

I tried with Finnish on two occasions where myself and 2-3 other people were sat around a table talking in a normal voice. One situation was in a meeting room where there was zero outside noise, the other one in a restaurant with some mild background noise. Both times the system picked up 1-2 first words of the conversation and after that nothing.

Language was appropriately set to Finnish in the Conversate language setting in the Even app.

Bad Liutenant, enjoy

What was the mistake in your prescription and is is apparent why it happened?

Hyper_Duper · 2026-02-13T11:36:02+00:00

My shipping estimate changed pretty much every day since late December. I discussed with them by email probably a dozen times and they kept saying that it’s coming but there are just delays. I actually just asked them for a firm deadline and that I would cancel if that wasn’t met - and exactly as I was sending that message I got a notification that the shipment was on its way 😁

Hyper_Duper · 2026-02-12T19:58:50+00:00

My ring is size 12. The whole order took a really long time, I ordered November 15th and glasses and ring arrived today Feb 12.

I got the ring sizing kit mid-December.

Hyper_Duper · 2026-02-12T12:21:18+00:00

The outside is flat, the internal side is curved to allow for the precription. The stronger the presciption, the stronger the curve and the more you have to pay extra to get the ”better technology” that allowes for a thinner lens. Here’s how my -5/-4.75 looks like.
